Legislation sounds very positive for the environment. The article does say that shooting ranges are exempt as they have lead/bullet recovery systems in place and this legislation is more about protecting waterways and forests from being (further) polluted with lead shot. Military and police are excluded probably for the same reason as almost all their shooting is on-range.

The article doesn’t mention and I was hoping someone knows - what’s the common alternative metals used for rifle rounds and shotgun shells? Steel balls for shotguns?

Does it make a big difference to shooting/ballistics, as the alternatives would be less-dense than lead?
